IV. Equipment design highlights

1. High temperature and high pressure resistant design

- 

Reinforced piping system: high-pressure stainless steel piping + ferrule sealing joints, resistant to 15MPa pressure and 100℃ high temperature.

- 

Rapid heating technology: PID temperature control algorithm, water temperature from room temperature to 80℃ in 30 minutes.

2. Intelligent control

- 

Multi-mode programming: support IPX9K standard mode, customized cycle test (e.g. high temperature → normal pressure → low temperature alternately).

- 

Fault self-diagnosis: automatically detect nozzle clogging, pump abnormality, heater failure, and prompt for solutions.

3. Energy saving and environmental protection

- 

Water circulation system: closed loop design, reuse after filtration, water saving rate ≥80%.

- 

Waste heat recovery: optional heat recovery module to reduce energy consumption (applicable to continuous testing scenarios).

V. Example of test flow (IPX9K standard)

1. 

Sample fixation: install the engine ECU on the test bench and adjust to a nozzle distance of 150mm.

2. 

Parameter setting: select IPX9K mode (80℃, 8MPa), set 4 spray angles (0°→30°→60°→90°).

3. 

Start the test:

◦ 

The equipment is automatically heated to 80°C and pressurized to 8MPa.

◦ 

Spraying at each angle for 30 seconds for a full 2 minutes.

4. 

Result determination: the ECU was disassembled to check whether there was water seepage inside and to test whether the electrical performance was normal.

VI. Selection Recommendations

Demand level

Recommended Configuration

Basic type

- Pressure 8MPa, temperature 80℃, manual angle adjustment, budget 300,000-500,000 yuan (domestic).

High-end type

- Pressure 10MPa, temperature 100℃, full-automatic multi-angle rotation, in line with ISO 20653, budget 800-1.5 million yuan (imported brands).

Customized Solutions

- Extra-large test chamber (1m×1m×1m), support for whole vehicle parts testing, integrated salt spray function, budget more than 2 million RMB.

VII. Maintenance and calibration

1. 

Daily maintenance:

◦ 

Empty the water stored in the line after each test to prevent high temperature scaling.

◦ 

Clean nozzles monthly (soak in dilute hydrochloric acid) and check seal aging.

2. 

Annual calibration:

◦ 

Pressure sensors, temperature probes, flow meters require third party calibration (ISO 17025 standard).

◦ 

Verify spray angle accuracy (error ≤ ±1°) and water temperature uniformity.
